土、水、大気に存在する窒素酸化物除去のためのバイオテクノロジー応用
Biotechnological Application for Removal of Nitrogen Oxides Present in Soil, Water and Atmosphere
21世紀の人口増加を支えるため、食料の生産量増加は喫緊の課題です。一方、肥料の生産・消費の増大に伴い、多くの反応性が高い窒素化合物が土壌、水、大気に流出し、富栄養化、飲料水汚染、温室効果ガスの増大が顕著になっています。このような窒素にまつわる環境問題の進行を抑制し、健全な窒素化合物の循環を支えているのが土壌、水に生息する微生物群になります。本講義では、窒素循環の環境微生物学で世界をリードするミネソタ大学の石井聡准教授をお招きし、土壌・水・大気に過多に存在する窒素化合物の負荷低減に向けた微生物の役割とそれを用いた技術に関してご講演頂きます。
日時：2023年12月6日（水）17：15～18：30
場所：小金井キャンパス 講義棟 L0013
講演は英語で行われます。お問い合わせは寺田（akte @ cc.tuat.ac.jp）まで。

Translated:
To support the population growth of the 21st century, increasing food production is an urgent challenge. On the other hand, as the production and consumption of fertilizers increase, many reactive nitrogen compounds flow into the soil, water, and air, leading to eutrophication, drinking water pollution, and an increase in greenhouse gases. Soil and water-dwelling microbial communities are responsible for suppressing the progression of such nitrogen-related environmental problems and supporting the healthy circulation of nitrogen compounds. In this lecture, we will invite Prof. Satoshi Ishii of the University of Minnesota, who is a world leader in environmental microbiology of nitrogen cycling, to give a lecture on the role of microorganisms in reducing the burden of nitrogen compounds that are excessively present in soil, water, and air, and the technologies using them.
